Midas XL4 Features
48 Mic Inputs.
Direct Outputs.
The XL4 features a new mic amplifier which further improves on the XL3 design giving increased
gain range and lower distortion whilst retaining the XL3's constant HF bandwidth topology which
assures excellent amplifiers stability, RF rejection and noise performance at all gains.
Every input module is fitted with a direct output as standard with its own level control and front
panel switching which selects the source from post fader, pre fader or pre insert and equaliser.
16 audio sub groups.
The 16 main audio groups can be assigned to any of the 8 automute groups and to VCA control
from any combination of the 2 motorised grand master faders. A safe switch is again included for
each group. The input for the groups is normally derived from the 16 group busses but for monitor
applications the fader change over routes the 16 mono aux busses to the group faders.
Equaliser.
Inserts.
The sonic performance of the legendary XL3 equaliser is maintained including the full parametric
mid's and traditional Midas bass and treble shelving responses. In addition the treble and bass
sections now have an extended frequency range and are switchable to full parametric operation.
Each channel has a half normalised fully balanced insert send and return point which can be
switched in or out from the front panel and set as either pre or post equaliser.
Input metering.
Audio busses.
These peak reading meters cover a 60dB range in 3dB steps and can be switched globally to
monitor pre fader signals or pre insert and equaliser signals.
Each channel can be routed to any combination of 42 audio busses comprising of 16 mono aux'es,
8 stereo aux'es, 16 stereo groups and 2 stereo masters. All this is switchable on the module front
panel but also via the automation control.
VCA and mute busses.
Each channel can be controlled by any combination of the 10 motorised VCA master faders and 8
mute masters. Assignment of these busses is again switchable on the module front panel or by the
automation control. A safe switch disconnects the channel from all mute groups and an isolate
switch removes the channel from all VCA control.
Line inputs.
A separate Hi Z line input with its own dedicated gain control is incorporated which is ideal for
playback of recorded material. Global change over from mic (record) to line (playback) is easy
because it is under automation control.
